The discovery was made during construction of a new path for cyclists running through Parkfield, linking High Street and Darkes Lane.

However, the Roman tile fragments which were found are nothing too new to the Potters Bar field, because similar pieces have been dug up and found before, most notably a Roman kiln found in the 1950s.

But more than half a century on, artefacts are still being found.

A spokesman for Hertsmere Borough Council said: “The pieces which have been found will be kept by us and displayed later at the air raid shelter in Parkfield which is going to be refurbished and used as an educational centre.”

Work on the new cycleway is due to be completed by the middle of this month.
